Principal Systems Design Architect

Stormentum Inc•Austin, TX

About The Position

Stormentum is hiring a systems-level architect to guide development of its distributed, modular power electronics conversion platform for data centers and microgrids. The role translates product requirements into engineering specifications, defines subsystem interactions, and guides hardware and firmware teams. The architect owns the system architecture connecting distributed power cells with energy storage, data center loads, generators, microgrids, and the electrical grid, from design through integration, certification, and production. The position leads system requirements and interface definition, system simulations, performance and safety testing, architectural trade-off analysis, risk assessment, design reviews, and third-party integrations. It also supports certification to applicable UL requirements and grid codes, serves as a technical liaison across product, engineering, customers, installers, utilities, and regulators, and manages the transition from design to manufacturing. The posting refers to the role as “Staff Systems Design Architect” in the About the Role section, while the listed job title is Principal Systems Design Architect.

Requirements

Master's degree in Electrical Engineering or Physics.
At least 5 years of experience in electrical systems design, including at least one full product cycle taking distinct products from concept to production.
Deep experience integrating power electronics systems with external interfaces such as the grid, energy storage, servers, microgrids, or distributed energy resources.
Experience with high-voltage power conversion systems at 400 V and above, such as grid-tied inverters, energy storage, EV charging, or industrial power equipment.
Deep experience building system-level electrical physics models in MATLAB/Simulink or similar tools, and analyzing topologies and component parameters to find optimal solutions to product-level requirements.
Breadth across high-voltage, low-voltage, mechanical, thermal, and communications domains.
Experience with processes similar to those outlined in UL 1998, UL 991, IEC 62477-1, and IEC 61508.

Nice To Haves

Experience collaborating on or leading Hazard and Risk Assessments and DFMEA.
Experience with data center power hardware, such as 480V AC three-phase and 800 VDC rack power systems or power shelves, or with modular multilevel converter architectures.
Experience with grid-tied inverter systems.
Knowledge of grid-forming inverter technologies and advanced grid-support functions.
Experience maintaining requirements within tools such as DOORS, Jama, or Polarion.
Familiarity with UL 62368-1, UL 1973, NFPA 855, UL 1741 SA/SB, IEEE 1547, and UL 9540.
Familiarity with international grid standards, including IEC or UL 62368-1.

Responsibilities

Define and decompose system-level requirements into hardware, firmware, controls, and integration specifications.
Develop and maintain system block diagrams and interface control documents.
Define system-level performance and safety test requirements and support development of automated test equipment.
Own and report on architectural trade-offs across high-voltage, low-voltage, mechanical, and communications domains.
Lead engineering teams through Hazard and Risk Assessment and support DFMEA, PFMEA, and safety test processes.
Design system integration architecture connecting the platform with energy storage, generators, data center and microgrid loads, and the electrical grid.
Run system-level simulations to evaluate design options and guide engineering decisions.
Lead the product through third-party integrations and support certification, including UL and applicable grid codes.
Serve as the primary technical liaison between product and engineering, translating customer, installer, utility, and regulatory requirements into engineering direction.
Lead system-level design reviews and risk assessments across subsystems.
Manage the handoff from design through manufacturing and ensure designs are optimized for production.
Collaborate with mechanical, firmware, controls, and hardware teams across the product lifecycle.
